The Sigma 60mm f/2.8 DN is a new mid-range telephoto lens for Micro Four Thirds and NEX system cameras. Offering a 35mm equivalent focal length of 90mm/120mm (NEX/MFT), the Sigma 60mm f/2.8 DN boasts a rounded aperture diaphragm and a minimum focus distance of 50cm. The lens benefits from a linear AF motor which moves the lens unit directly without the need for gears or other extra mechanical parts. This system ensures accurate and quiet focusing, the company says. The Sigma 60mm f/2.8 DN lens takes small 46mm filters and comes supplied with an LH520-03 lens hood (see picture).
